THRASHlNG-MACHINE.

Specification lorining part of Letters Patent No. 13,97 I, dated August 30, 186

"To all whom, it may concern:

Be it known that I, L.. N. CLARK, of

l-h-ighton, in the county of Livingston and State of Michigan, have invented new and useful Improvements in Thrashing-Machines; and I do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being bad to the accompanying draw:

ings, making part of this specification, in which- Figure l is a top view. Fig. 2 is a side view in the same position as that shown in -Fig.' 1, and Fig. 3 is a side view in another position.

Like letters refer to like parts in the-several views.

In order to make the nature of my invention obvious, it will be necessary for me firstto describe the modes in common use. They are usually composed of two sections of nearly uniform length, united by hook-hinges when in operation, and attached to the'separator by hook and eye and driven by a band or chain around the pulley at the upper end for the purpose of giving motion to the endless-belt elevator. These straw-carriers are generally inadcot' one, or, at most, two sec -tions, and have to be elevated and depressed by hand, and when it, is necessary to move the stacker It will require four men to do it.

In my improved.straw-carricr for thrashin'g-machines the carrier is permanently atta-ched to the separator, and is composed of three sections of any desirable length by ob serving the relative proportions shown at A B C. The endlessbelt carrier is drivenfroni apulley at its base with a band extending to' the top, and iseasily adjustable from the ground. The upper end of the carrier is supported, elevated, or depressed by niea-ns of a rope or chain, l), upon each side of the carrier. The lower ends of these ropes are atby means of a strong articulating joint, or,

rather, the lower roller thatv carries the andless belt has its journal-boxes so formed as to furnish the requisite support and articulation, and imperfectly shown at H. The section it is joined to the section A by means of a hinge-joint, B, and the section (J is hinged to the section B by the hinge-joint C. The hinges 15 are placed upon the lower side of the elevator, and the hinges O are placed upon the upper side, in order that the carrier may have firmness when extended, and also that it may be folded upon itself, as seen in Fig. 3, in order for transportation. \Vhen the carrier is thus folded, it is secured together by hooks, and the rope D is placeds the carrier-frame and around a similar roller,

J, at -the .upper endof section 0. The end- .less carrier-belt is shown at K, and has slats placed transversely upon its surface to carry up the straw. The supporting-rope D is attached to section 0, near its lower end. The gravity of the upper end keeps the joint 0 firm andsteady, while the tension upon the rope D kecps'the joint B firm and steady when extended.

In (rder to unfold the carrier, unhook the hooks upon each side which assist in holding the sections together, unt'asten the Windlass, and carry out the sections B and G to a horizontal position. Now, by a proper adjustment of" the rope D, by turning the Windlass by means of the wheel F, the carrier can be elevated to. any desired position and changed at pleasure, by turning the Windlass, without stopping the machine. The endless belt is put in motion by'a band from any convenient part of the thrashing-machine passing. around the pulley 1 upon the shaft 1, and in consequence of this shaft I being the articulating point of the carrier, the elevation or depression of the upper end will not change the in elevating and depressing the same. i
